RADIATOR ATTACHMENT.

Application filed October 31, 1924. Serial No. 747,027.

This invention relates to improvements in radiator structures for motor-driven machines and vehicles, and especially to those types of motor-driven vehicles which are designed to do extremely heavy work, such as tractors, heavy trucks and farm ma-- chinery.

This invention has for its object to provide a simple but eflicient radiator attachment which will increase the circulation and cooling efficiency of the radiator, and will thoroughly strain all water or liquid. admitted to the upper tank of the radiator in circulation or when the tank is filled.

More specifically, it is an object in such a device to provide an enlarged upper radiator tank adapted to be superimposed upon a standard radiator core, said tank being equipped with a removable filter box in the top thereof and also having means therein for preventing the water or liquid insaid tank from undue splashing.

It is a further object to provide in this device a vapor box disposed within said tank directly above the water level and having screened communication with the damp air at the top of said tank, and provided with a conduit communicating with the intake to the carburetor of the machine or vehicle engine.

To these ends, generally stated, my invention consists of the novel devices and combinations of devices herein described and pointed out in the claims.-

The preferred form of my invention is illustrated in the accompanying drawings, wherein like notations refer to similarparts throughout the several views, and in which- Hg. 1 is a rear view of the attachment applied to the top of a standard radiator core for the most part in vertical section, some parts being shown in elevation;

Fig.2 is a vertical Section taken on the line 22 of Fig. 1, showing the attachment connected with the water jacket of a gasoline engine; and

Fig. 3 is a plan view of the attachment, with some parts broken away.

Referring to tli e drawings, a standard tubular radiator core is designated by the numeral 4, and the usual water jacket of an explosive engine by the numeral 5. A rec tangular open bottom casing 6 having a projecting flange 6 around its bottom is superimposed on the radiator core 4 and tightly secured to the top thereof to make a water tight connection therewith. The top of the radiator core, therefore, forms the bottom of the upper radiator tank, the walls of which are afforded by the casing 6. A pair of obliquely and downwardly inclined baflle plates 7 are secured and project from two opposite walls of easing 6 on the interior thereof, upon which bafile plates a removable, preferably rectangular, filter box 8 is adapted to be supported. This filter box has a screened or perforated bottom 9 and an open top and is adapted to fit closely within the upper walls of casing 6. The usual water outlet 10 from the water jacket 5 of the engine is connected to an intake pipe 11 extending upwardly and downwardly to communicate with the top of the tank or casing 6 above the filter box 8, and preferably centrally thereof. A suitable union or connecting member 12 is employed in the upper portion of pipe 11 to facilitate the connection of the downwardly disposed portion thereof. A vapor box 13 is disposed within the top portion of the casing 6 directly above the screen 9 of the filter box and comprises a rectangular, casing having vertical walls and having a screened top and bottom through which air may be admitted to the interior thereof. A bent conduit 14 communicates with the interior of the vapor box 13 and is shown connected for communication with the air intake pipe X of the carburetor of'the engine. Conduit 14 may, of course, be connected directly with the manifold Y of the engine, if desired, instead of said carburetor air intake. A two-piece cover is provided for easing 6, the two portions of which are adapted to be slid into oppositely disposed flanged guides 15 secured to the top of casing 6. One portion 16 of the cover is imperforate having a central concave portion at its inner end adapted to partially surround the intake pipe 11. The other portion of the cover 17 has a rectangular opening therein atits central part and a slot- 18 at the outer side thereof connecting therewith, through which opening and slot the vapor box 13 with its outlet conduit 14 is disposed into the top of easing 6. Vapor box 13 is, moreover, supported from the cover 17 by means of a small flange 13 engaging said cover about the edges of the rectangular aperture therein. A hinged cover 19 is mounted on the flange 15 adapted to protect and cover the top of vapor box 13, and is preferably of concave cross section to permit air from the outside of the casing to be admitted to the vapor box 13 1 around the ends thereof, as indicated by the the top ofcover 17. Then theunion 12 is arrows.

When it is desired to clean the filter box, the vapor box 13 is first removed with its conduit 14 through the aperture and slot m unscrewed and the water intake conduit removed. when the cover may be slid ofl' and the filter box taken out. b

By means of vapor box 13, a supply of moist air will always be available to the carburetor, which is well known to improve the explosive mixture admitted to the engine. The screened top and bottom of vapor box 13 will admit the damp air from the water in casing 6, but will obviously exclude all dirt and foreign material from the interior thereof.

The tank or casing 6 permits a greater amount of water to be stored for circulation through the radiator, thus insuring better cooling and increased circulation.

The danger of the water splashing about or out of casing-6 is overcome by means of the oppositely disposed bafiie plates 7.

All water admitted to the core of the radiator will be thoroughly strained through the filter box 8 and all particles of rust or p other foreign material will be prevented rangement of parts without departing from the scope of the invention.

While the vapor box 13 is illustrated as disposed within the top portion of the cas ing 6 supported by the cover 17 it may be mounted on the top of cover 17 directly over the rectangular opening whereby the slot 18 in the cover will not be necessary and whereby it may be removed by sliding the cover 17 off of the end of the casing 6. The cover 19 for the vapor box will, of "course, then be hinged to the top edge of the vapor box.

T'Vhat is claimed is 1. In combination with an internal combustion engine, a radiator therefor, a core in said radiator, a casing constituting an upper radiator tank adapted to be mounted on the radiator core, a removable filtering box mounted across the top of said casing, an intake pipe leading fromthewater jacket of tlie egg'ine to the top of said casing above said tering box whereby the water from the water jacket will be filtered before en- 'tering said radiator core.

chine, of a radiator attachment comprising a casing superimposed above the core of said radiator, a vapor box of smaller dimensions mounted at the top of said main casing and having a screened bottom and top, and a conduit in communication with the interior thereof adapted to be connected to the fuel mixture of the engine.

4. The combination with a standard radiator and engine of a. motor-driven machine, of a. radiator attachment comprising an open bottom casing superimposed above the core of said radiator, a removable filter box extending across the top of said casing, an intake pipe from the water jacket of said engine communicating with the interior of said casing above the filter box, oppositely disposed baflle plates projecting obliquely downward from opposite sides of said casing adapted to prevent liquid within said casing from splashing and adapted to support said filter box, and a removable cover for said casing.

5. The structure set forth in claim 4;, and a vapor box having a screened bottom and top mounted in said casing above said filter 'box, means for admitting air into said vapor box, and a conduit communicating with said vapor box and adapted to be connected to the air intake pipe of the carburetor of the engine.

6. The combination with a radiator and engine of a motor driven machine, of a radiator attachment comprising a casing super-imposed above the core of said radiator, a vapor box mounted at the top of said casing and having a perforated side and a conduit in communication with the interior of said box and adapted to be connected to the intake of the carburetor of the engine.

In testimony whereof I 'atfix my signature.
